匈牙利命名规则
https://idleloop.com/hungarian/
Charles Simonyi 匈牙利记谱法的创造者 在微软公司工作时研发出来
您可以找到 2000年~2004年的 Directx SDK source code 符合这种写作方式
匈牙利人名和大多数其他欧洲人名相比是反过来的，即姓氏在名字的前面。
举个例子，英语化的名字“Charles Simonyi”在匈牙利语中原本是
“Simonyi Karoly”。 这与中文名字是一样的
它是一种语义学用在程式写作上
语义学（英语：semantics）也作语意学，是对指称、意义或真理的研究；语义学
涉及了语言学、逻辑学、计算机科学、自然语言处理、认知科学、心理学等
诸多领域。
有两种匈牙利表示法。
系统匈牙利语 和 应用程序匈牙利语
使用应用匈牙利符号来命名语义更好
匈牙利语命名语义分为 3 个部分
1.
种类 从最接近目的名的种类至最远的目的名种类
在简短的命名时可以跳过种类
2.
集合的缩写 或 代表意思的缩写。
3.
目的缩写
类似于告诉你的老板这个命名是什么用途
范例:
(a)
PT_WRITE_COMMAND is a point structure.
structure T must at fisrt. if point structure then PT at first
PT_WRITE_COMMAND aptwcShare[8];
等同
T_WRITE_COMMAND* aptwcShare[8];
a = array -> type abbreviation of close to far from purpose.
p = point -> type of the middle distance from purpose
t = struct -> type of the far distance from purpose
wc = WRITE_COMMAND -> set abbr.
Share = purpose
(b)
int nPort;
n = number -> meaning abbr.
Port = purpose
(c)
const char aszProtocol[8]
a = array -> type abbreviation close to far from purpose.
sz = string zero ending -> meaning abbr.
Protocol = purpose
const can skip
(d)
class member
int m_iCount;
static variable
int s_iCount;
global variable
int g_iCount;

Linus Torvalds linux 创始者的看法
https://www.kernel.org/doc/html/v4.10/process/coding-style.html
Encoding the type of a function into the name (so-called Hungarian notation)
is brain damaged - the compiler knows the types anyway and can check those,
and it only confuses the programmer. No wonder MicroSoft makes buggy programs.

Do not use Hungarian notation
Do not abbreviate
Do not prefix enums, classes, or delegates with any letter

它在微软的历史
https://en.wikipedia.org/wiki/Talk%3AHungarian_notation
Systems Hungarian was banned from the Windows NT project by its chief
architect Dave Cutler. His decision to do this was correct, in my opinion.
The best counter-example for the usefulness of Hungarian notation is IMHO
provided by Microsoft themselves. From How To Write Unmaintainable Code:
One followon trick in the Hungarian notation is "change the type of a
variable but leave the variable name unchanged". This is almost invariably
done in windows apps with the migration from Win16 WndProc(HWND hW, WORD
wMsg, WORD wParam, LONG lParam) to Win32 WndProc(HWND hW, UINT wMsg, WPARAM
wParam, LPARAM lParam) where the w values hint that they are words, but they
really refer to longs. The real value of this approach comes clear with the
Win64 migration, when the parameters will be 64 bits wide, but the old "w"
and "l" prefixes will remain forever.

But you might want to heed the latest advice from Microsoft, the company
where Hungarian Notation originated. Since 2008, their General Naming
Conventions have included this simple note:
[DO NOT use Hungarian notation.] 出处如下
General Naming Conventions

Word Choice
DO choose easily readable identifier names.
For example, a property named HorizontalAlignment is more English-readable
than AlignmentHorizontal.
DO favor readability over brevity.
The property name CanScrollHorizontally is better than ScrollableX (an
obscure reference to the X-axis).
DO NOT use underscores, hyphens, or any other nonalphanumeric characters.
[DO NOT use Hungarian notation.]
AVOID using identifiers that conflict with keywords of widely used
programming languages.

请问各位的公司还使用 Hungarian Notation?
※ 引述《fatalfeel2 (风在动)》之铭言：
: 程式命名规则 与 Makefile
: 1. 查阅了 ISO 1999 C99, ISO 2011 C++, ISO 2014 C++, ISO 2020 C++,
: https://reurl.cc/gZGz6L
: https://reurl.cc/XLGlq0
: ISO都有基本的命名规则
: 另查阅 微软 安卓 程式规范
: 微软 的 命名规则偏向 The Hungarian Naming Convention
: 由2001 制定完整规范, prefix 如ch, sz, p
: https://idleloop.com/hungarian/
: 2. variable prefix naming convention 一定是正确的吗?
